How to display single encrypt record?

I use encrypt. I can display all table data. However I can'T get one record. I don't encrypt 'id'. I tried another column but same.

Here is my error

Trying to get property 'id' of non-object

Here is my code

blade file (I click this link first )

<a href="one?id="></a>

blade file (display page I got error at this page)

@foreach ($data as $val)    

@endforeach

Trying to get property 'id' of non-object

web.php

Route::get('/one','MailController@onerecord');
Route::post('/one','MailController@onerecord');

Controller

public function onerecord(Request $request)
 { 
$id = $request['id'];
$data = Contact::where('id',$id)->get();
return view('mail.one', ['data' => $data]); 
}

Could you teach me what is wrong my code please?
